A Road Map for ‘How to Get There From Here’

The introduction and adoption of any new technology can be a difficult process. Broadband Internet service is considered so useful that more and more people want to set up networks in their home to share a broadband connection. Wireless technology has removed one of the barriers to networking—running wires. It allows more people to try networking while at the same time exposes them to the inherent complexity of networking. General networking concepts, setup, and maintenance can be difficult to understand. In addition, wireless technology adds issues, such as range, interference, signal quality, and security to the picture.

September 2004 202-10042-01

Chapter 3

Installing the XE102 and the WGX102

This chapter describes how to set up the XE102 and WGX102 on your local area network (LAN) and connect to the Internet. There are two operation modes for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102 — Access Point Mode and Router Mode. The WGX102 can be used immediately with no further configuration in Access Point Mode as described in this chapter and in the WGX102 Installation Guide.

T o use the WGX102 in Router Mode, you must perform some basic configuration, as described in

Chapter 4, “Configuring the WGX102 in Router Mode”.

Follow these instructions to set up your range extender.

Prepare to Install Your Range Extender

• Do not connect the WGX102 or the XE102 into a power strip, extension cord, uninterruptable power supply (UPS), or surge protector as this may prevent the range extender from working properly or degrade the network performance.

• Each computer that will use the WGX102 Wall-Plugged Range Extender must have a wireless card installed and configured.

• Observe the wireless placement and range guidelines in “Observing Performance, Placement,

and Range Guidelines” on page 5-1.

• For Cable Modem Service: When you perform the range extender setup steps be sure to use the computer you first set up your cable Internet connection.

• For DSL Service: You may need information such as the DSL login name/e-mail address and password in order to complete the range extender setup.

Before proceeding with the range extender installation, familiarize yourself with the contents of the NETGEAR 54 Mbps Wall-Plugged Wireless Range Extender WGX102 Resource CD (240-10088-01), especially this manual and the animated tutorials for configuring networking on PCs.

Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102

Note: The WGX102 is designed for easy installation in access point mode, and can be used with

multiple XE102 W all-Pl ugged Ethernet Bridges in this mode. However , if you choose to configure the WGX102 in Router Mode, you can only use one XE102 and you must be sure of the correct IP addresses during the configuration procedure.

WGX102 Wall-Plugged Range Extender Operation Modes

The WGX102 can be immediately used without configuration in Access Point Mode, or can perform more functions in Router Mode. With Router Mode installation, the WGX102 functions as the only router in the network.

Access Point Mode

In Access Point Mode, the WGX102 acts as an Access Point for your wireless devices, and provides a means of communication between your wireless LAN and wall-plugged LAN. In this configuration, the WGX102 wall plug connection becomes a LAN port and the DHCP server is disabled. T o use the WGX102 in Access Point Mode, you will need to have another device such as a router with DHCP enabled in order to access the Internet.

September 2004 202-10042-01

Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102

Router Mode

In Router Mode, the WGX102 provides all the functions of Access Point Mode, plus the following services:

• Shared Internet Access — the wall plug port becomes the WAN port, and if a broadband modem is connected to it through an XE102, the WGX102 can provide Internet access to your entire wireless LAN.

• DHCP Server — the WGX102 can act as DHCP (Dynamic Host Configuration Protocol) server, which provides the IP address and other TCP/IP configuration for the all the computers that are connected to the range extender through the wireless network. In Router Mode, using this feature is recommended, and it is enabled by default.

Chapter 5

Wireless Configuration

This chapter describes how to configure the wireless features of your WGX102 Wall-Plugged Range Extender. In planning your wireless network, you should consider the level of security required. You should also select the physical placement of your range extende r in order to maximize the network speed. For further information on wireless networking, refer to

Appendix D, “Wireless Networking Basics”.

Observing Performance, Placement, and Range Guidelines

The operating distance or range of your wireless connection can vary significantly bas ed on the physical placement of the range extender. The latency, data throughput performance, and notebook power consumption of wireless adapters also vary depending on your configuration choices.

Note: Failure to follow these guidelines can result in significant performance

degradation or inability to wirelessly connect to the range extender. For complete range/ performance specifications, please see Appendix A, “Technical Specifications”.

For best results, place your range extender:

• Near the center of the area in which your computers will operate.

• Away from sources of interference, such as computers, microwaves, and 2.4 GHz cordless phones.

• Away from large metal surfaces.

The time it takes to establish a wireless connection can vary depending on both your security settings and placement. Connections using WEP or WPA can take slightly longer to establish. Also, WEP and WPA encryption can consume more battery power on a notebook computer.

Implementing Appropriate Wireless Security

Note: Indoors, computers can connect over 802.11b/g wireless networks at ranges of up

to 300 feet. Such distances can allow for others outside of your immediate area to access your network.

Unlike wired network data, your wireless data transmissions can be received well beyond your walls by anyone with a compatible adapter. For this reason, use the security features of your wireless equipment. The WGX102 Wall-Plugged Range Extender pro vides highly effective security features that are covered in detail in this chapter. Deploy the security features appropriate to your needs.

Wireless Data Security Options

There are several ways you can enhance the security of your wireless network.

• Restrict Access Based on MAC address. You can restrict access to only trusted computers so that unknown computers cannot wirelessly connect to the WGX102. MAC address filtering adds an obstacle against unwanted access to your network, but the data broadcast over the wireless link is fully exposed.

• Turn Off the Broadcast of the Wireless Network Name SSID. If you disable broadcast of the SSID, only devices that have the correct SSID can connect. This nullifies the wireless network “discovery” feature of some products such as Windows XP, but the data is still fully exposed to a determined snoop using specialized test equipment like wireless sniffers.

• WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared Key authentication and WEP data encryption will block all but the most determined eavesdropper.

• WPA-PSK. Wi-Fi Protected Access (WPA) data encryption provides strong data security. WPA-PSK will block eavesdropping. Because this is a new standard, wireless device driver and software availability may be limited.

Basic Wireless Settings

To configure the Wireless settings of your range extender, click the Wireless link in the main menu of the browser interface. The Wireless Settings menu appears, as shown below.

5-2 Wireless Configuration

September 2004 202-10042-01

Figure 5-1: Wireless Settings menu

• Name (SSID). The SSID is also known as the wireless network name. Enter a value of up to 32 alphanumeric characters. In a setting where there is more than one wireless network, different wireless network names provide a means for separating the traffic. Any device you want to participate in a particular wireless network will need to use this SSID for that network. The WGX102 default SSID is: NETGEAR.

• Broadcast of Name (SSID). If you disable broadcast of the SSID, only devices that have the correct SSID can connect. Disabling SSID broadcast nullifies the wireless network ‘discovery’ feature of some products such as Windows XP.

• Region. This field identifies the region where the WGX102 can be used. It may not be legal to operate the wireless features of the range extender in a region other than one of those identified in this field.

• Channel. This field determines which operating frequency will be used. It should not be necessary to change the wireless channel unless you notice interference problems with another nearby access point. For more information on the wireless channel frequencies please refer to

“Wireless Channels” on page D-7.

Wireless Configuration 5-3

September 2004 202-10042-01

Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102

• Mode. This field determines which data communications protocol will be used. You can select “g only,” “b only,” or “g and b.” “g only” dedicates the WGX102 to communicating with the higher bandwidth 802.11g wireless devices exclusively. “b only” dedicates the WGX102 to communicating with the higher bandwidth 802.11b wireless devices exclusively. The “g and b” mode provides backward compatibility with the slower 802.11b wireless devices while still enabling 802.11g communications.

• Wireless Card Access List. When the Trusted PCs Only radio button is selected, the WGX102 checks the MAC address of the wireless station and only allows connections to computers identified on the trusted computers list.

• Security Options. These options are the wireless security features you can enable. The table below identifies the various basic wireless security options. A full explanation of these standards is available in Appendix D, “Wireless Networking Basics”.

2. In the Router Upgrade menu, click the Browse button and locate the upgrade file.

3. Click Upload.

Note: When uploading software to the WGX102 Wall-Plugged Range Extender, it is important not to interrupt the Web browser by closing the window, clicking a link, or loading a new page. If the browser is interrupted, it may corrupt the software. When the upload is complete, your range extender automatically restarts. The upgrade process typically takes about one minute.

In some cases, you may need to reconfigure the range extender after upgrading.

Changing the Administrator Password

Note: Before changing the WGX102 password, use the backup feature to save your configuration settings. If after changing the password, you forget the new password you assigned, you will have to reset the WGX102 back to the factory defaults to be able to log in using the default password of password. This means you will have to restore all the range extender configuration settings. If you ever have to reset the WGX102 back to the factory defaults, you can restore your settings from the backup.

The default password for the WGX102 Web browser interface is password. NETGEAR recommends that you change this password to a more secure password.

From the main menu of the browser interface, under the Maintenance heading, select Set Password to bring up the menu shown below.

Content Filtering in Router Mode

This chapter describes how to use the content filtering features of the 54 Mbps Wall-Plugged Wireless Range Extender WGX102 to protect your network. These features are only available if you are running the WGX102 in Router Mode. See Chapter 4, “Configuring the WGX102 in

Router Mode” for more information on Router Mode configuration.

Content Filtering Overview

The 54 Mbps Wall-Plugged Wireless Range Extender WGX102 provides you with Web content filtering options, plus browsing activity reporting and instant alerts via e-mail. Parents and network administrators can establish restricted access policies based on time of day, Web addresses and Web address keywords. You can also block Internet access by applications and services, such as chat or games.

To configure these features of your range extender, click on the subheadings under the Content Filtering heading in the main menu of the browser interface. The subheadings are described below:

Blocking Access to Internet Sites

The WGX102 W all-Plugged Range Extender allows you to restrict access based on Web addresses and Web address keywords. Up to 255 entries are supported in the Keyword list.

Keyword application examples:

• If the keyword “XXX” is specified, the URL <http://www.badstuff.com/xxx.html> is blocked.

• If the keyword “.com” is specified, only Web sites with other domain suffixes (such as .edu or .gov) can be viewed.

• If you want to block all Internet browsing access during a scheduled period, enter the keyword “.” and set the schedule in the Schedule menu.

Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102

Blocking Access to Internet Services

The WGX102 Wall-Plugged Range Extender allows you to block the use of certain Internet services by PCs on your network. This is called services blocking or port filtering. The Block Services menu is shown below:

Figure 7-2: Block Services menu

Services are functions performed by server computers at the request of client computers. For example, Web servers serve Web pages, time servers serve time and date information, and game hosts serve data about other players’ moves. When a computer on your network sends a request for service to a server computer on the Internet, the requested service is identified by a service or port number. This number appears as the destination port number in the transmitted IP packets. For example, a packet that is sent with destination port number 80 is an HTTP (Web server) request.

T o enable service blocking, select either Per Schedule or Always, then click Apply. If you want to block by schedule, be sure that a time period is specified in the Schedule menu.

Content Filtering in Router Mode 7-3

September 2004 202-10042-01

Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102

To specify a service for blocking, click Add. The Add Services menu appears, as shown below:

Figure 7-3: Add Services menu

From the Service Type list, select the application or service to be allowed or blocked. The list already displays several common services, but you are not limited to these choices. To add any additional services or applications that do not already appear, select User Defined.

Configuring a User Defined Service

To define a service, first you must determine which port number or range of numbers is used by the application. The service numbers for many common protocols are defined by the Internet Engineering Task Force (IETF) and published in RFC1700, “Assigned Numbers.” Service numbers for other applications are typically chosen from the range 1024 to 65535 by the authors of the application. This information can usually be determined by contacting the publisher of the application or from user groups of newsgroups.

Enter the Starting Port and Ending Port numbers. If the applicatio n uses a single port number , enter that number in both boxes.

If you know that the application uses either TCP or UDP , select the appropriate protocol. If you are not sure, select Both.

• Send to this e-mail address Enter the e-mail address to which logs and alerts are sent. This e-mail address is also used as the From address. If you leave this box blank, log and alert messages are not sent via e-mail.

You can specify that logs are automatically sent to the specified e-mail address with these options:

• Send alert immediately Select this check box if you would like immediate notification of attempted access to a blocked site.

• Send logs according to this schedule Specifies how often to send the logs: Hourly, Daily, Weekly, or When Full.

– Day for sending log

Specifies which day of the week to send the log. Relevant when the log is sent weekly or daily.

– Time for sending log

Specifies the time of day to send the log. Relevant when the log is sent daily or weekly.

If the Weekly, Daily or Hourly option is selected and the log fills up before the specified period, the log is automatically e-mailed to the specified e-mail address. After the log is sent, the log is cleared from the router’s memory. If the router cannot e-mail the log file, the log buffer may fill up. In this case, the WGX102 overwrites the log and discards its contents.

The WGX102 Wall-Plugged Range Extender uses the Network Time Protocol (NTP) to obtain the current time and date from one of several Network Time Servers on the Internet. In order to localize the time for your log entries, you must specify your Time Zone:

•Time Zone Select your local time zone. This setting is used for the blocking schedule and for time-stamping log entries.

• Daylight Savings Time Select this check box if your time zone is currently under daylight savings time.

Chapter 8

Advanced Configuration of the WGX102

This chapter describes how to configure the advanced features of your 54 Mbps Wall-Plugged Wireless Range Extender WGX102 in Router Mode. These features can be found under the Advanced heading in the main menu of the browser interface.

Note: If you are unfamiliar with networking and routing, refer to Appendix B,

“Network, Routing, Firewall, and Basics”, to become more familiar with the terms and

procedures used in this chapter.

• If you are using the WGX102 Wall-Plugged Range Extender in Access Point Mode, the only Advanced menu option is LAN IP Setup and the configuration options are different than the Router Mode options. See “Configuring the LAN IP Setup Options in Access Point Mode” on

page 3-10 for more information.

• If you are using the WGX102 Wall-Plugged Range Extender in Router Mode, you will see additional Advanced features such as Port Forwarding and Triggering, WAN Setup, Dynamic DNS, Static Routes, Remote Management, and UPnP. These features are described in the following sections.

Configuring Port Triggering

Note: This feature and the rest of the features in this chapter are only displayed if you are using the WGX102 in Router Mode. See Chapter 4, “Configuring the WGX102 in

Router Mode” for more information on Router Mode configuration.

Port Triggering is an advanced feature that can be used to easily enable gaming and other internet applications. Port Forwarding is typically used to enable similar functionality, but it is static and has some limitations.

Note: If you use applications such as multi-player gaming, peer-to-peer connections, real time

communications such as instant messaging, or remote assistance (a feature in Windows XP), you should also enable UPnP according to the instructions at “Configuring Universal Plug and Play

(UPnP)” on page 8-17.

Advanced Configuration of the WGX102 8-1

September 2004 202-10042-01

Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102

Port Triggering opens an incoming port tempo rarily and d oes not require the server on the Internet to track your IP address if it is changed by DHCP, for example. Port Triggering monito rs outbound traffic. When the range extender detects traffic on the specified outbound port, it remembers the IP address of the computer that sent the data and triggers the incoming port. Incoming traffic on the triggered port is then forwarded to the triggering computer.

Using the Port Triggering page, you can make local computers or servers available to the Internet for different services (for example, FTP or HTTP), to play Internet games (like Quake III), or to use Internet applications (like CUseeMe).

Port Forwarding is designed for FTP, Web Server or other server based services. Once port forwarding is set up, requests from the Internet are forwarded to the proper server. On the contrary, port triggering only allows request from Internet after a designated port is 'triggered'. Port triggering applies to chat and Internet games.

Figure 8-1: Port Triggering menu

This table lists the current rules:

• Enable — indicates if the rule is enabled or disabled. Generally, there is no need to disable a rule unless it interferes with some other function, such as Port Forwarding.

• Name — the name for this rule.

• Outgoing Ports — the port or port range for outgoing traffic. An outgoing connection using one of these ports “Triggers” this rule.

8-2 Advanced Configuration of the WGX102

September 2004 202-10042-01

Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102

• Incoming Ports — the port or port range used by the remote system when it responds to the outgoing request. A response using one of these ports is forwarded to the PC that triggered this rule.

To see which rules are currently being used, click the Status button. The following data is displayed:

• Rule — the name of the Rule.

• LAN IP Address — the IP address of the PC currently using this rule.

• Open Ports — the Incoming ports which are associated the this rule. Incoming traffic using one of these ports is sent to the IP address above.

• Time Remaining — the time remaining before this rule is released, and thus available for other PCs. This timer is restarted whenever incoming or outgoing traffic is received.

Before starting to configure an Internet Game or Application, you need to know which service, application or game you will be configuring. Also, you need to have the outbound port (triggering port) address for this game or application.

Follow these steps to set up a computer to play Internet games or use Internet applications:

1. Click Add.

Figure 8-2: Add Port Triggering Rule menu

2. For the Name, enter a suitable name for this rule (the name of the application).

3. Enable the rule.

5. For the Incoming (Response) Port Range, enter the range of port numbers used by the remote system when it responds to the PC's request.

6. Click Apply to save your changes.

Configuring Port Forwarding to Local Servers

Although the range extender causes your entire local network to appear as a single machine to the Internet, you can make a local server (for example, a Web server or game server) visible and available to the Internet. This is done using the Port Forwarding menu. Fr om the main menu of the browser interface, under Advanced, click Port Forwarding to view the port forwarding menu, shown below.

Figure 8-3: Port Forwarding menu

Use the Port Forwarding menu to configure the range extender to forward incoming protoc ols to computers on your local network. In addition to servers for specific applications, you can also specify a Default DMZ Server to which all other incoming protocols are forwarded. The DMZ Server is configured in the WAN Setu p menu as discussed in “Configuring the WAN Setup

Options” on page 8-7.

Before starting, you need to determine which type of service, application or game you will provide and the IP address of the computer that will provide each service. Be sure the computer’s IP address never changes. To configure port forwarding to a local server:

September 2004 202-10042-01

Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102

Note: To assure that the same computer always has the same IP address, use the reserved IP address feature of your WGX102 W all-Plugged Range Extender. See “Using Address

Reservation” on page 8-12 for instructions on how to use reserved IP addresses.

1. From the Service & Game box, select the service or game to host on your network. If the service does not appear in the list, refer to the following section, “Adding a Custom

Service”.

2. Enter the IP address of the local server in the corresponding Server IP Address box.

3. Click the Add button.

Adding a Custom Service

To define a service, game or application that does not appear in the Services & Games list, you must determine what port numbers are used by the service. For this information, you may need to contact the manufacturer of the program that you wish to use. When you have the port number information, follow these steps:

1. Click the Add Custom Service button.

Figure 8-4: Ports - Custom Services menu

2. Type the service name in the Service Name box.

3. Type the beginning port number in the Starting Port box.

• If the application uses only a single port; type the same port number in the Ending Port

box.

• If the application uses a range of ports; type the ending port number of the range in the

Ending Port box.

4. Type the IP address of the computer in the Server IP Address box.

5. Click Apply to save your changes.

Local Web and FTP Server Example

If a local computer with a private IP address of 192.168.0.33 acts as a Web and FTP server, configure the Ports menu to forward HTTP (port 80) and FTP (port 21) to local address

192.168.0.33.

In order for a remote user to access this server from the Internet, the remote user must know the IP address that has been assigned by your ISP. If this address is 172.16.1.23, for example, an Internet user can access your Web server by directing the browser to http://172.16.1.23. The assigned IP address can be found in the Router Status menu, where it is shown as the WAN IP Address.

Some considerations for this application are:

• If your account’s IP address is assigned dynamically by your ISP, the IP address may change periodically as the DHCP lease expires.

• If the IP address of the local computer is assigned by DHCP , it may change when the computer is rebooted. To avoid this, you can manually configure the computer to use a fixed address.

• Local computers must access the local server using the computers’ local LAN address (192.168.0.33 in this example). Attempts by local computers to access the server using the external IP address (172.16.1.23 in this example) will fail.

Multiple Computers for Half Life, KALI or Quake III Example

To set up an additional computer to play Half Life, KALI or Quake III:

1. Click the button of an unused port in the table.

2. Select the game again from the Services/Games list.

3. Change the beginning port number in the Start Port box. For these games, use the supplied number in the default listing and add +1 for each additional computer. For example, if you've already configured one computer to play Hexen II (using port 26900), the second computer's port number would be 26901, and the third computer would be 26902.

4. Type the same port number in the End Port box that you typed in the Start Port box.

5. Type the IP address of the additional computer in the Server IP Address box.

Some online games and videoconferencing applications are incompatible with NAT. The WGX102 Wall-Plugged Range Extender is programmed to recognize some of these applications and to work properly with them, but there are other applications that may not function well. In some cases, one local computer can run the application properly if that computer’s IP address is entered as the default in the Ports menu. If one local computer acts as a game or videoconferencing host, enter its IP address as the default.

Configuring the WAN Setup Options

The WAN Setup options let you configure a DMZ server, change the MTU size and enable the range extender to respond to a Ping on the WAN port. These options are discussed below.

Figure 8-5: WAN Setup menu.

Connect Automatically, as Required. Normally, this option should be selected. An Internet connection will be made automatically after each timeout, whenever Internet-bound traffic is detected. This provides connection on demand and is potentially cost-saving in places in Europe for example where Internet services charge by the minute.

If disabled, you must connect manually, using the Connection Status button on the Router Status screen. This manual connection stays up all the time without timeouts.

Disable SPI Firewall. The Stateful Packet Inspection (SPI) Firewall protects your LAN against Denial of Service attacks. This should only be disabled in special circumstances.

Advanced Configuration of the WGX102 8-7

September 2004 202-10042-01

Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102

Default DMZ Server. The default DMZ server feature is helpful when using some online games and videoconferencing applications that are incompatible with NAT. The WGX102 is programmed to recognize some of these applications and to work properly with them, but there are other applications that may not function well. In some cases, one local computer can run the application properly if that computer’s IP address is entered as the default DMZ server.

Note: DMZ servers pose a security risk. A computer designated as the default DMZ server loses much of the protection of the firewall, and is exposed to exploits from the Internet. If compromised, the DMZ server can be used to attack your network.

Incoming traffic from the Internet is normally discarded by the WGX102 unless the traffic is a response to one of your local computers or a service that you have configured in the Ports menu. Instead of discarding this traffic, you can have it forwarded to one computer on your network. This computer is called the Default DMZ Server.

To assign a computer or server to be a Default DMZ server, follow these steps:

1. Click WAN Setup link on the Advanced section of the main menu.

2. Type the IP address for that server. To remove the default DMZ server, replace the IP address numbers with all zeros.

3. Click Apply.

Respond to Ping on Internet WAN Port. If you want the WGX102 to respond to a 'ping' from the Internet, select the Respond to Ping on Internet WAN Port check box. This should only be u sed as a diagnostic tool, since it allows your range extender to be discovered. Do not select this check box unless you have a specific reason to do so.

MTU Size. The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 Bytes, 1492 Bytes for PPPoE connections, or 1436 for PPTP connections. For some ISPs you may need to reduce the MTU. But this is rarely required, and should not be done unless you are sure it is necessary for your ISP connection.

Any packets sent through the range extender that are larger than the configured MTU size are repackaged into smaller packets to meet the MTU requirement. To change the MTU size:

1. Under MTU Size, enter a new size between 64 and 1500.

2. Click Apply to save the new configuration.

Configuring the LAN IP Setup Options in Router Mode

LAN IP Setup is under the Advanced heading on both the Access Point Mode and Router Mode menus. If you are using the WGX102 in Access Point Mode, see “Configuring the LAN IP Setup

Options in Access Point Mode” on page 3-10 for configuration information.

This menu allows configuration of LAN IP services such as DHCP and RIP in Router Mode. From the main menu of the browser interface, under Advanced, click LAN IP Setup to view the LAN IP Setup menu, shown below.

Figure 8-6: LAN IP Setup menu in Router Mode

The range extender’s default LAN IP configuration is:

• LAN IP addresses—192.168.0.101

• Subnet mask—255.255.255.0

These addresses are part of the IETF-designated private address range for use in private networks, and should be suitable in most applications. If your network has a requirement to use a different IP addressing scheme, you can make those changes in this menu.

Advanced Configuration of the WGX102 8-9

September 2004 202-10042-01

Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102

The LAN IP parameters are:

• IP Address This is the LAN IP address of the range extender.

• IP Subnet Mask This is the LAN Subnet Mask of the range extender. Combined with the IP address, the IP Subnet Mask allows a device to know which other addresses are local to it, and which must be reached through a gateway or router .

• RIP Direction RIP (Router Information Protocol) allows a router to exchange routing information with other routers. The RIP Direction selection controls how the WGX102 sends and receives RIP packets. Both is the default.

— When set to Both or Out Only, the WGX102 broadcasts its routing table periodically. — When set to Both or In Only, it incorporates the RIP information that it receives. — When set to None, it does not send any RIP packets and ignores any RIP packets received.

• RIP Version This controls the format and the broadcasting method of the RIP packets that the WGX102 sends. (It recognizes both formats when receiving.) By default, this is set for RIP-1.

— RIP-1 is universally supported. RIP-1 is probably adequate for most networks, unless you

have an unusual network setup.

— RIP-2 carries more information. Both RIP-2B and RIP-2M send the routing data in RIP-2

format.

• RIP-2B uses subnet broadcasting.

• RIP-2M uses multicasting. Multicasting can reduce the load on non-router machines because they do not listen to the RIP multicast address and do not receive the RIP packets. However, if one router uses multicasting, then all routers on your network must use multicasting.

Note: If you change the LAN IP address of the WGX102 while connected through the browser, you will be disconnected. You must then open a new connection to the new IP address and log in again.

8-10 Advanced Configuration of the WGX102

September 2004 202-10042-01

Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102

Using the WGX102 as a DHCP server

By default, the WGX102 functions as a DHCP (Dynamic Host Configuration Protocol) server, allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to the range extender's LAN. The assigned default gateway address is the LAN address of the WGX102. IP addresses are assigned to the attached computers from a pool of addresses specified in this menu. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.

For most applications, the default DHCP and TCP/IP settings of the range extender are satisfactory. See “IP Configuration by DHCP” on page B-10 for an explanation of DHCP and information about how to assign IP addresses for your network.

If another device on your network is the DHCP server, or if you manually configure the network settings of all of your computers, clear the ‘Use router as DHCP server’ check box. Otherwise, leave it selected.

To specify the pool of IP addresses to be assigned, set the Starting IP Address and Ending IP Address. These addresses should be part of the same IP address subnet as the range extender’s LAN IP address. Using the default addressing scheme, you should define a range between

192.168.0.2 and 192.168.0.253, although you may want to save part of the range for devices with fixed addresses.

The WGX102 delivers the following parameters to any LAN device that requests DHCP:

• An IP Address from the range you have defined

• Subnet Mask

• Gateway IP Address (the range extender’s LAN IP address)

• Primary DNS Server (if you entered a Primary DNS address in the Basic Settings menu; otherwise, the range extender’s LAN IP address)

• Secondary DNS Server (if you entered a Secondary DNS address in the Basic Settings menu)

Using Address Reservation

When you specify a reserved IP address for a computer on the LAN, that computer always receives the same IP address each time it accesses the range extender’s DHCP server . Reserved IP addresses should be assigned to servers that require permanent IP settings.

To reserve an IP address:

1. Click the Add button.

2. In the IP Address box, type the IP address to assign to the computer or server (choose an IP address from the range extender’s LAN subnet, such as 192.168.0.x).

3. Type the MAC Address of the computer or server. (Tip: If the computer is already present on your network, you can cop y its MAC address from the Attached Devices menu and paste it here.)

4. Type a Device Name of your choosing.

5. Click Apply to enter the reserved address into the table.

Note: The reserved address is not assigned until the next time the computer contacts the range

extender's DHCP server. Reboot the computer or access its IP configuration and force a DHCP release and renew.

To edit or delete a reserved address entry:

1. Click the button next to the reserved address you want to edit or delete.

2. Click Edit or Delete.

Configuring Dynamic DNS

If your network has a permanently assigned IP address, you can register a domain name and have that name linked with your IP address by public Domain Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP address, you will not know in advance what your IP address will be, and the address can change frequently. In this case, you can use a commercial dynamic DNS service, which allows you to register your domain to their IP address, and forward traffic directed at your domain to your frequently-changing IP address.

Note: If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x),

the dynamic DNS service will not work because private addresses will not be routed on the Internet.

The WGX102 contains a client that can connect to many popular dynamic DNS services. You can select one of these services and obtain an account with them. Then, whenever your ISP-assigned IP address changes, your range extender automatically contacts your dynamic DNS service provider, log in to your account, and register your new IP address.

To configure Dynamic DNS:

1. From the main menu of the browser interface, under Advanced, click Dynamic DNS.

2. Register for an account with one of the dynamic DNS service providers whose names appear in the ‘Select Service Provider’ box. For example , for dyndns.org, go to http://www.dyndns.org.

3. Select the Use a dynamic DNS service check box.

4. Select the name of your dynamic DNS Service Provider.

5. Type the Host Name (or domain name) that your dynamic DNS service provider gave you.

6. Type the User Name for your dynamic DNS account.

7. Type the Password (or key) for your dynamic DNS account.

8. If your dynamic DNS provider allows the use of wildcards in resolving your URL, you may select the Use wildcards check box to activate this feature. For example, the wildcard feature causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org

9. Click Apply to save your configuration.

Configuring Static Routes

Static Routes provide additional routing information to your range extender. Under normal circumstances, the WGX102 has adequate routing information after it has been configured for Internet access, and you do not need to configure additional static routes. You must configure static routes only for unusual cases such as multiple routers or multiple IP subnets located on your network.

3. Select Private if you want to limit access to the LAN only. The static route will not be reported in RIP.

4. Select Active to make this route effective.

5. Type the Destination IP Address of the final destination.

6. Type the IP Subnet Mask for this destination. If the destination is a single host, type 255.255.255.255.

7. Type the Gateway IP Address, which must be a router on the same LAN segment as the WGX102.

8. Type a number between 1 and 15 as the Metric value. This represents the number of routers between your network and the destination. Usually, a setting of 2 or 3 works, but if this is a direct connection, set it to 1.

9. Click Apply to have the static route entered into the table.

Static Route Example

As an example of when a static route is needed, consider the following case:

• Your primary Internet access is through a cable modem to an ISP.

• You have an ISDN rout er on your home network for connecting to the company where

you are employed. This router’s address on your LAN is 192.168.0.100.

• Your company ’s network is 134.177.0.0.

When you first configured your WGX102, two implicit static routes were created. A default route was created with your ISP as the gateway, and a second static route was created to your local network for all 192.168.0.x addresses. With this configuration, if you attempt to access a device on the 134.177.0.0 network, your range extender forwards your request to the ISP. The ISP forwards your request to the company where you are employed, and the request will likely be denied by the company’s firewall.

In this case you must define a static route, telling your range extender that 134.177.0.0 should be accessed through the ISDN router at 192.168.0.100. The static route would look like Figure 8-8.

In this example:

• The Destination IP Address and IP Subnet Mask fields specify that this static route applies to all 134.177.x.x addresses.

• The Gateway IP Address fields specifies that all traffic for these addresses should be forwarded to the ISDN router at 192.168.0.100.

• A Metric value of 1 will work since the ISDN router is on the LAN.

• Private is selected only as a precautionary security measure in case RIP is activated.

Enabling Remote Management Access

Using the Remote Management page, you can allow a user or users on the Internet to configure, upgrade and check the status of your WGX102 Wall-Plugged Range Extender.

Note: Be sure to change the range extender's default configuration password to a very secure password. The ideal password should contain no dictionary words from any language, and should be a mixture of letters (both upper and lower case), numbers, and symbols. Your password can be up to 30 characters.

To configure your range extender for Remote Management:

1. Select the Turn Remote Management On check box.

2. Specify what external addresses are allowed to access the range extender’s remote management.

Note: For enhanced security, restrict access to as few external IP addresses as practical. a. To allow access from any IP address on the Internet, select Everyone.

b. To allow access from a range of IP addresses on the Internet, select IP address range.

Enter a beginning and ending IP address to define the allowed range.

c. To allow access from a single IP address on the Internet, select Only this computer.

Enter the IP address that is allowed access.

3. Specify the Port Number to use for accessing the management interface. Web browser access normally uses the standard HTTP service port 80. For greater security,

change the remote management Web interface to a custom port by entering that number in the box provided. Choose a number between 1024 and 65535, but do not use the number of any common service port. The default is 8080, which is a common alternate for HTTP.

4. Click Apply to have your changes take effect.

Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102

Note: When accessing your WGX102 from the Internet, type your range extender's WAN IP address into your browser's Address (in IE) or Location (in Netscape) box, followed by a col on (:) and the custom port number. For example, if your external address is 134.177.0.123 and you use port number 8080, you must enter http://134.177.0.123:8080 in your bro wser.

Configuring Universal Plug and Play (UPnP)

Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access the network and connect to other devices as needed. UPnP devices can automatically discover the services from other registered UPnP devices on the network.

From the main menu of the browser interface, under Advanced, click UPnP. Set up UPnP according to the guidelines below.

Figure 8-9. UPnP menu

Turn UPnP On: UPnP can be enabled or disabled for automatic device configuration. The default setting for UPnP is disabled. If disabled, the range extender does not allow any device to automatically control the resources, such as port forwarding (mapping), of the range extender.

Note: If you use applications such as multi-player gaming, peer-to-peer connections, real time communications such as instant messaging, or remote assistance (a feature in Windows XP), you should enable UPnP.

Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102

Advertisement Period: The Advertisement Period is how often the WGX102 broadcasts its UPnP information. This value can range from 1 to 1440 minutes. The default period is 30 minutes. Shorter durations ensure that control points have current device status at the expense of additional network traffic. Longer durations may compromise the freshness of the device status but can significantly reduce network traffic.

Advertisement Time To Live: The time to live for the advertisement is measured in hops (steps) for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is allowed to propagate for each UPnP advertisement before it disappears. The number of hops can range from 1 to 255. The default value for the advertisement time to live is 4 hops, which should be fine for most home networks. If you notice that some devices are not being updated or reached correctly, then it may be necessary to increase this value a little.

UPnP Portmap Table: The UPnP Portmap Table displays the IP address of each UPnP device that is currently accessing the WGX102 and which ports (Internal and External) that device has opened. The UPnP Portmap Table also displays what type of port is opened and if that port is still active for each IP address.
